What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Sinn 903 St II

The Sinn 903 St II is widely praised for its robust build quality, over-engineered feel, and strong value proposition, featuring 200 meters of water resistance and a La Joux-Perret L110 column-wheel chronograph movement. Owners appreciate the hybrid ceramic lume and the practical functionality of the slide rule operated by the bezel. However, reviewers note that the busy slide-rule dial can make time-reading challenging, with some finding the chronograph hand's placement over the "12" numeral less refined. On balance, owners and reviewers rate the Sinn 903 St II highly for its exceptional build quality and value, particularly its robust water resistance and functional slide rule at its price point.

Spinnaker Hass Automatic

The Spinnaker Hass Automatic is a 43mm watch featuring an NH35 movement and sapphire crystal, with owners highlighting its beautiful dial. Some find Spinnaker watches, including this model, to be on the thicker side, with one owner describing the Hass X MCS Blue Fade variant as comically large and chunky. The Spinnaker Hass Automatic was offered at $445 USD as part of a special collection with customized elements, and a limited edition of 200 pieces was also available for $195 shipped. On balance, owners and reviewers note the attractive dial as a key positive, though some express reservations about the watch's thickness.
